As shown in Figure 3 the upof the wall of said rod seat being omitted to pro- 55 vide clearance for pivotal movement of said third point support.

2. In combination, a one piece brake beam fulcrum having an aperture forming a pivotal seat for a third point support casting, a third point support casting pivotally carried by said seat, said fulcrum having an aperture therein adjacent said first mentioned aperture forming a substantially enclosed tension member seat, a portion of the wall of said tension member seat being omitted to provide clearance for pivotal movement of said third point support.

3. In combination, a brake beam fulcrum provided at one end with aligned openings, a third point support pivoted in said aligned openings, a substantially enclosed tension member seat formed in said fulcrum adjacent said aligned openings, the wall of said enclosed seat being omitted to provide clearance for pivotal movement of said third point support.

4. In combination, a brake beam fulcrum provided at one end with aligned openings, a third pointsupport pivoted in said aligned opening, a substantially enclosed tension member seat formed in said .fulcrum adjacent said aligned openings, the wall of said enclosed seat being omitted to provide clearance for pivotal movementof said third point support, said enclosed seat being tapered from its mid-point toward the outer ends thereof.

5. In combination, a brake beam fulcrum having a substantially enclosed tension member seat, lugs extending from the opposite ends of said seat, said lugs being provided with aligned openings, a third point support journalled in said aligned openings, the enclosing wall of said seat being partially omitted to provide clearance for limited pivotal movement of said third point support.

6. A brake beam fulcrum having an enclosed tension member seat, said fulcrum being provided with extensions at the opposite ends of said seat, said extensions having aligned openings, a third point support journalled in said openings, said extensions being aligned with said tension member seat longitudinally of said fulcrum, said seat having reinforcing top and bottom webs between said extensions.

7.. In combination, a brake beam fulcrum having a substantially enclosed tension member seat, said fulcrum being provided with extension-s at the opposite ends of said seat, said extensions having aligned openings and a third point support pivoted in said aligned openings, said seat having reinforcing top and bottom web members between said extensions, said web members serving to limit the pivotal movement of said third point support.

8. A brake beam fulcrum having a substantially enclosed rod seat elongated in the direction of the longitudinal axis of said fulcrum, said fulcrum being provided with extensions at the opposite ends of said rod seat, said extensions having aligned openings, a third point support journalled in said openings, said extensions being aligned with said rod seat longitudinally of said fulcrum, said rod seat having top and bottom web members between said extensions.

9. In a brake beam fulcrum having a substantially enclosed rod seat, said fulcrum being provided with extensions at the opposite ends of said rod seat, said extensions having aligned openings, a third point support journalled in said openings, and said rod seat being partially omitted between said extensions.

'10. In combination, a brake beam fulcrum having a rod seat enclosed at its opposite ends, said fulcrum including extensions from the enclosed ends of said seat, a third point support journalled in said extensions, said rod seat including top and bottom walls intermediate said extensions constituting reinforcements thereof and permitting limited pivotal movement of said third point support.

11. A brake beam fulcrum having a substantially enclosed tension member seat, said fulcrum being provided with extensions at the opposite end of said seat, said extensions having aligned openings, a third point support journalled in said openings, said seat having reinforcing top and bottom webs between said extensions, one of said webs extending beyond the other of said webs towards the end of said fulcrum.

12. A brake beam fulcrum having a substantially enclosed tension member seat, said fulcrum being provided with extensions at the opposite end of said seat, said extensions having aligned openings, a third point support journalled in said openings, reinforcing Web members between said extensions serving to limit the pivotal movement of the third point support, one of said webs extending closer to the end of the fulcrum than the other of said webs.

13. In combination, a brake beam fulcrum having a substantially enclosed tension member seat, said fulcrum being provided with extensions at the opposite ends of said seat, said extensions having aligned openings and a third point support pivoted in said aligned openings and means formed integral with said fulcrum comprising top and bottom web members extending from said seat between said extensions, one of said web members extending closer to the end of said fulcrum than the other of said web members.
